FRANCIS B U IQR, SHELBY, OHIO,-

Be it known that I, FRANCIS BRUoKER,-.a

citizen of the United States, residing at- Shelby, Ohio, have invented certain new and 3 useful Im rovements in Washing-Machines, ofzwl ich t e following is a specification.

My invention relatesto improvements in washing machines of-that' type in which a suitably-supported tub is rotated or 'osc'il' latedl by the operator and the clothes are subjected to the "actionpf 'a rubber held within the tub against rotary movement;

I have aimed to provide a device of "this character which shall be simple,"s'trong, and

durable, convenient of man pulation; and effective in operation. q The invention is illustrated in the accompanying drawings, inwhieh Figure lis a front elevation. Fig. 2 is a side elevation, partly in section. Fig 2 is a.

Fig. 5 is a detail plan. viewof the spring of. this form; and Figs. 6 and 7 are detail views in plan and side .ele'vation;"respectively, showing theattachmentfor a second tub.

. In the drawings, the tub, which is rotatably" mounted in the manner hereinafter described upon thehu'b ZOf a stand orsu'pport. This standor sup port I prefer to form in the manner shown in the drawings, in which four supporting Inem bers are used which arepreferably of tubular form. 'Two of these supporting membersor legs 3 are inclined "toward "the "hub" and curved inwardly at their upper ends, where they may be secured to the hub by'a screwthread connection or in any other suitable manner. The other two" suppOrtingiriem. bers or standards 4*are located 'on a' line outside of the periphery of the tub" and extend vertically to a height somewhat above the top of the tub. They are connected to the hub by radial members "5, also-oftubul'ar construction, and are connected together and to the legs 3 by a single continuous rod 6, Whichis threaded through openings in the legs and standards. The standards, it desired, may be constructed each in two parts connected by a QI ''1 coupling 4*, to which coupling the corresponding arm 5 will also be connected. The standards at their upper ends are connected by a horizontal bar 7, which serves not only to further brace the ee rat e. of tte R r a Application filed December 29, 1904. SerialNo. 238,783.

"I: refer to support the tub-upon a spider, whidli consists of aplateor castin "8*; having a's"'1ndle;9,"passing down throng the hubl an held against being lifted out' bya'reinov able key '10." I" preferably provide *ahtifriction-balls I1 between a bearing disk fi on; the underside of, the plate and a-correspond-" ing bearing surface"13"on the upper-endof the hub The plate 8'is preferably formed of cast-iron, sothat'the parts "whichare liable to breakto wit, thsha'ft or spi-ndle 9 l and steel, and by being p aced inthe mold at the time ofcasting the plate :8 may bemade practicallyintegraltherewith. Thesespiders arms are radially arrangedandrovided'a't their outer ends with" ret'ainingugs for engaging the outer periphery of.-thei='"tub*. "A spring 15- encircles the ab, and I hav'efound 5 it extremely desirable to-so 'arrange 'this-"and connect-it with the sup minplate or-spider l that'the movementof t e tub-in either direc- *tion from its-neutral position-willy tendto 'windu' the springfi To- 'rovidefonthiaI cause t etw'o ends- 15 oft espring'to cross each other and extend a lug or projection 16 ffrom the-hub between the =cro ssedfeniis.= corres onding lu'g'or projection*"17"-extends 5-fr6m I of: the springs but at a distance-'fi'om the cem *ter differing from that of the 'lug16-,'='so- -as not to contact" therewith. It wilhthus be seenthat'if the tub" is rotated to the right, forinstanc, the lug 17 willbeafagains't' the right' hand" end of the spring while the *other end will be held against'rotationby the-lug I 16, and the spring-:will"'bewound as' the tub rotates in that direction. 'Gonversely'flf the tub is r'o'tate'd' to thelft, the lug-' H-will carry with i t the ieit' handend 1 5- bf'th'e spring, while the o'ther end will be held against 3 rotation by the lug 1 6', and the spr" wi again be if xi l 1A7. r!

Instead of forming the-hub in the manner just described and placing the sprin upon the outer side of the same I may form t e hub e plate 8between these crossed'ends spring 15 within the hub. In this event I place upon the upper end of the hub a cap 2, upon which the spider part 8 rotates, this part 2 being secured to the hub 2 so as to be non-rotatable. Lugs 16 and 16 project, respectively, from the .cap' 2 and the lower part of the hub or casing, while corresponding lugs 17 and 17 carried by a sleeve 17 on the spindle 9, project, respectively, upward and downward into the same horizontal plane as the lugs 16 and 16 The spring 15 at each end is provided with-a portion which is brought inwardly across the faces of the pairs of lugs thus described and has a curved portion 15 partly encircling the spindle. From the arrangement described and illustrated it will be seen that the operation is precisely the same as in the formpreviously or held in a central position by a vertical I described. The rubber 18 is preferably provided with a tubular portion 19, extending up through the cover of the tub, and this tubular portion may conveniently be guided spindle 20, secured to the bottom of the tub. The upper end of the tubular portion 19 is provided with a bifurcation 20", which is designed to be engaged by a pivoted arm 21. The opposite end of this arm 21 is pivoted in a forked. bracket 22, which has a shank 23, secured in the upper end of one of the tubular standards. The fork portion is extended rearwardly of the standard, as shown at 24, and the pivot 25 of the arm is located in this laterally-extended portion, so that the arm may be swung over and dropped down out of the way in the position shown in dotted lines when the rubber and clothes are to be removed from the tub.

I deem it advisable to provide a stand for an auxiliary tub, and this is conveniently done by pivoting two members or bars 26 to the vertical standards at a suitable height,

. connecting their outer ends by a bar 27, to the mental stand may be folded in out of the way when not in use.

A very simple and effective manner of securing the ribs (1 in the tub is shown in Figs. 2 and 2*, which obviates nailing through the bottom of the tub or putting a false bottom in the tub' with ribs fastened to it.

It will be noticed that an annular groove orrecess is made in the staves of the tub on the inside near the bottom. This can be I made so that the rubbing-ribs will be level on top, or they can be inclined, if it is desired, by placing the groove nearer or farther away from the bottom of the tub. It is of great advantage to have a space between the ribs and the bottom of the tub to allow a free passage of water to assist in removing the dirt from the clothes during the rubbing process.

The rubbing-ribs a are placed in the proper position in the tub, with their outer ends in the groove, as shown, and spacing-pieces e are placed in the groove from one rib to the next to hold them the proper distance apart. At the center I provide a piece (1, rabbeted out, as shown, lapping over the ends of the ribs secured to the bottom of the tub by the clamping-collar b, threaded on the rod 20, as shown, which holds all the inner ends of the ribs in their proper place and secures them to the bottom of the tub. Another advanta e is the easy way of replacing the ribs should they become in any way defective. Nails in the bottom of the tub are objectionable, as they soon cause the wood to decay and in pialny cases cause the wood to split, causing a Having thus described my invention, what I claim is 1. In a washing-machine, a rotary tub, a

I stand supporting the same and composed of tubular members, one of said members extending vertically to above the tub, a fork having its shank fitted in the end of said upwardly-extended member, said fork having its arms extended to the rear of the supportjing member, an arm pivoted to said rearwardly-extended parts of the arms, and a rubber within the tub having a part adapted to be detachably engaged by said arm, substantially as described.

2. In a washing-machine, a stand having a hub, a tub-support rotatably carried thereby, a lug or projection extending upwardly at one side of the hub, a projection on the tubsupport, and a helical spring encircling the hub and having its ends crossed and extending on opposite sides of said projections, substantially as described.

3. In a washing-machine, the combination with the stand and tub rotatably mounted thereon, said stand having a vertical member extending above the top of the tub, of a cover for said tub, having a central opening,

' a rubber having a tubular spindle projecting through said opening, a guide-rod extending from the bottom of the tub up within said spindle, and an arm pivotally connected to said vertical member and detachably engaging said spindle, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
